Title: Electric vacuum bottle
Inventor: YUJI YASUHIRO
IPC: A47J27/21
Filed: 1989-09-08
Abstract: PURPOSE:To prevent a bottle in which hot water is boiled and a danger to discharge the hot water occurring by providing an optical path through which light from a light emitting element passes to a water pipe corresponding to the upper and lower limit positions of a water quantity in a hot water bath, and controlling the energizing of a heater by transmitting or blocking the light with a water ball ascending/descending corresponding to a water level. CONSTITUTION:When the water quantity in the hot water bath 1 is between the lower limit A and the upper limit B within regulation, the optical paths formed between reflecting mirrors 10b and 10c, and between the reflecting mirror 10a and a light receiving element 9b are released, therefore, the light from the light emitting element 9a arrives at the light receiving element 9b, then, the heater is energized. At such a case, when the water quantity in the hot water bath 1 is decreased. the water ball 8 in the water pipe 7 descends. When the water level arrives at the lower limit A, the light from the light emitting element 9a is blocked, and no light arrives at the light receiving element 9b. The energizing of the heater 5 is therefore, stopped with a control circuit 11, which prevents the bottle in which the hot water is emptied boild. Also, when water over a regulation level is supplied to the hot water bath 1, the water ball 8 also,ascends, and when the water level arrives at the upper limit B, the light from the light emitting element 9a is blocked. The energizing of the heater 5 is therefore, stopped, which prevents the discharge of the hot water 3 from an upper cover 2 or a water outlet 4 occurring.

Abstract: PROBLEM TO BE SOLVED: To necessitate almost no redesigning for mass-produced products by setting an operating threshold of a transistor constituting a non-volatile memory to such a one as to keep the transistor in an off-state even if it is written with on-data. SOLUTION: An FPGA(field programmable gate array) assembled with devices is tested for actual operations such as electrical characteristics, operating characteristics, etc., (51). Then, the device assembling program data for the FPGA stored in an external memory is read (52). Next, ions are implanted into a channel formation region of each transistor to conduct a preprocess (53). Then, a switching, transistor corresponding to the '1' data in a memory cell region is turned to an off state according to the FPGA program data to set a threshold value to such a high one that makes rewriting impossible (54). After an afterprocess of the FPGA (55), data is written to keep the FPGA in a '0' state.
